We common people usually have a saying: Double top diameter, head circumference, and abdominal circumference are used to judge men and women. Many pregnant women are curious about this statement. So, is the measurement of biparietal diameter, head circumference, and abdominal circumference accurate for both men and women? How to measure men and women? Next, the editor will introduce these contents one by one, hoping to be helpful to everyone. Please listen to the editor's introduction.
Is the measurement of biparietal diameter, head circumference, and abdominal circumference accurate for men and women
It is not accurate to use biparietal diameter to determine whether the fetus is male or female. The determination of a baby's gender is somewhat related to the biparietal diameter bone length, but it cannot be solely based on the biparietal diameter femur length to determine fetal gender.
The general way to determine the gender of a fetus is as follows: subtract the length of the femur from the biparietal diameter, and if the result is greater than 21mm, it is considered a son; otherwise, it is considered a daughter. The reason is that boys have long heads and short legs, while girls have long legs and small heads.
Many people use the above methods to determine the gender of a fetus, so how accurate is it? In fact, this method has no scientific basis. The biparietal diameter and femur length are only indicators of fetal development and have nothing to do with fetal gender. Therefore, pregnant mothers can only use them as entertainment and should not take them seriously.
How to measure the biparietal diameter, head circumference, and abdominal circumference for men and women
Firstly, biparietal diameter, also known as BPD, refers to the biparietal diameter of the fetal head. It refers to the length of the widest part between the left and right sides of the fetal head, also known as the "head transverse diameter". Doctors often use it to observe the development of children, determine whether there is a head and pelvis imbalance, and ensure a smooth delivery.
Secondly, at full-term pregnancy, it should reach 9.3 centimeters or more. According to the general rule, after 5 months of pregnancy, the BPD basically matches the month of pregnancy, which means that at 28 weeks (7 months) of pregnancy, the BPD is about 7.0 centimeters, at 32 weeks (8 months), it is about 8.0 centimeters, and so on. After 8 months of pregnancy, an average weekly growth of about 0.2 centimeters is considered normal. When the expected production date cannot be determined through CRL in the initial stage, it is often predicted through BPD; After the mid-term, when estimating fetal weight, it is often necessary to measure this data.
The above is some content introduced by the editor about the measurement of head circumference and abdominal circumference for men and women with double top diameter. I hope it is helpful to everyone. Have you gained any new understanding of this topic after listening to my introduction? In fact, this statement lacks a certain degree of scientific validity, so there is no need to believe or take it too seriously. In fact, giving birth to boys and girls is the same, the important thing is that both the mother and the baby are safe and healthy.
